UNITED STATES ARTHUR H. SCHWARTZ, OF LOS ANGELES, CALIFORNIA CONTAINER AND CLOSURE MEANS THEREFOR Application filed January 17, 1981. Serial No. 509,332.

This invention relates to improvements in containers and closure means therefor.

The general object of the invention is to provide an improved container. 5 A further object is to provide a novel closure for containers.

An additional object of the invention is to provide a novel container and closure which is particularly adapted for holding medicines or acids which are detrimentally affected by contact with metal.

Another object of the invention is to provide an improved collapsible container and closure member therefor.

A further object is to provide an improved medicinal container which may be used as a syringe for injectin medicines into various ducts of the human ody.

A specific object of the invention is to provide a novel collapsible container and closure member made of a resilient material such as rubber. 8 I Other. objects and advantages'of this invention willbe apparent from the following description taken in connection with the accompanying drawing wherein:

Fig. 1 is an elevation of my improved container and closure member.

Fig. 2 is a view similar to closure member removed.-

Fig. 3 is a top plan view of the device shown in Fig. 2.

Fig. 4 is an enlarged fragmentary central vertical section through the container and closure member. f

Fig. 5 is an enlarged view of the discharge nozzle partly in section.

Fig. 6 is an enlarged central vertical section through the closure member, and

Fig. 7 is a fragmentary sectional view of a modification.

Referring to the drawing by reference charactors I have indicated. my improved device generally at 10. As shown this device comprises a container 12 and a closure member or cap 13. The container 12 comprises a body portion 14 which is preferably made of a good grade of rubber vulcanized to the desired elasticity and a discharge nozzle 15 made of a 3 Fig. 1 with the good grade of rubber which may be vulcanized slightly harder than the body portion 14.

' The container body 14 is shown as cylindrical in cross section and includes side walls 16 and a rounded lower end 17. At the upper end the side walls merge into a thickened up-v per portion 18 on which is provided a reduced collar 19. The inner face of the thickened portion18 is preferably conically shaped as indicated at 20 and converges towards a reduced aperture 21 provided in the collar 19.

The discharge nozzle 15 includes a conically shaped body portion 22 having an arcuate side wall which converges upwardly where it merges into a reduced conically shaped tip 23. Extending from the lower end of the body portion 22 I provide a reduced neck 24 which is cylindrical for a distance and then is provided with an outwardly flared portion 25, the taper of which substantiallycorresponds to the taper of the conically shaped portion 20 of the container body.

Extending through the discharge nozzle body 22 the tip 23 and the neck 24 I provide an aperture 26, and in the portion 25 I provide a conically shaped recess 27 which com municates with the aperture 26. v

To operatively position the discharge nozzle 15 on the body 14 the collar 19 is stretched to enlarge theaperture 21 and the outwardly flared portion 25 of the nozzle is inserted through the aperture into the interior of the body 14. When the nozzle 25 is thus operatively positioned on the body 14 the neck 24 of the nozzle is positioned in the aperture 21 of the body '14 and the tapered surface of the nozzle portion 25 engages the tapered surface of the conically shaped portion 20 of the body 14 and the upper surface of the collar 19 engages the under surface of the conical portion 22 of the nozzle, as clearly shown in Fig. 4. The resiliency of the parts holds them securely assembled.

The. cap 13 comprises a conically shaped hollow body portion 30 which is preferably made of a good grade of rubber vulcanized to the desiredelasticity, and which is of less interior diameter than the outer diameter of the nozzle 15. Adjacent the lower open end of the cap 13 I provide an inwardly extend ing flange 31 which includes an inner shoulder 32.

The container 12 is preferably filled with the desired contents by inserting a hollow instrument through the nozzle aperture 26. After the container has been filled the cap 13 is positioned on the discharge nozzle 15. To position the cap 13 on the discharge nozzle 15 the cap is forced down over the nozzle and in so doing the elasticity of the cap allows it to stretch and the cap flange 31 is forced over the base of the conical body 22 0f the discharge nozzle until the inner shoulder 32 of the cap engages the under surface of the base of the nozzle body 22 as clearly shown in When the cap 13 is thus positioned on the discharge nozzle 15 the cap is under tension and tightly engages the nozzle 15. When the cap 13 is on the nozzle 15 pressure on the container will force the contents thereof up througn. the nozzle aperture 26 against the inner surface of the end of the cap and thereby eXert an upward pressure on the cap which puts the cap under greater tension and thereby causes the cap to more tightly grip the nozzle 15 and prevent the contents from squeezing down between the nozzle and the cap. If desired the container12 may be made in one piece with the body 14 and nozzle 15 formed integral.

In Fig. 7 I have shown a slight modification of my invention wherein the discharge nozzle 15 and the cap 13 are used in combination with a container 35 which may be a paper milk container. The container 35 is made of a plurality of layers of treated paper and at the upper end is tapered as at 36 to conform to the taper of the nozzle portion 25. The conical ortion 36 merges into a reduced collar 37 w ich is preferably of a greater thickness than the walls of the container and 1s reinforced by a-plurality of bands such as wire 38.

To operatively position the discharge nozzle 15 on the container 35 the outwardly flared portion 25 of the nozzle is distorted and com pressed and forced through the neck 37 until the nozzle portion enters the container and resumes its correct shape whereupon the outer tapered surface of the nozzle portion 25 engages the tapered inner surface of the comcal portion 36 of the container 35. The container 35 is then filled and the cap 13 positioned on the nozzle 15. To remove the contents of the container 35 the cap 13 is removed and the contents withdrawn from the container through the aperture 26 in the discharge nozzle.

From the foregoing description it will be apparent that I have provided a novel container and closure therefore which is simple in construction and. highly efiicient in use.
